BackPack 2 Battery for MR1 and R1
Combine MR/R1 with our optional BackPack II and you will be able to enjoy MR1/R1 away from mains power. Placing batteries inside MR1/R1 would steal valuable speaker capacity, but BackPack II allows MR1/R1 to retain its rich mains powered performance with the benefit of complete portability.
A total evolution of the original, BackPack II attaches seamlessly to MR1/R1 and once fitted can be left permanently in place as it charges automatically whenever mains power is re-applied. A full charge will provide up to twelve hours of mains free listening depending on volume.
